Quickly and easily install a 4-way trailer connector on your Toyota T100 Pickup with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required. Converter is made using SMT to ensure superior performance.
This custom-fit T-connector plugs into your Toyota T100 Pickup's wiring harness, which is located either behind the driver's-side and passenger's-side tail light assemblies or behind the rear bumper along the frame rail.
Once installation is complete, the 4-way connector will be stowed beneath your Toyota T100 Pickup, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.
A tail light converter is built into this T-connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your Toyota T100 Pickup's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your Toyota T100 Pickup operate.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Today we're going to review part number C55513. This is the Curt T-Connector Vehicle Wiring Harness with the 4-Pole Flat Trailer Connector. This is a custom fit part number. It is designed to fit the 1993 to 1998 Toyota T100 pickup and the Toyota Tacoma model starting in 2005. What I would recommend is go to the product page of this part number on our website and at the bottom of the product page it will list the exact years and models that this will fit on. This is a quickly and easily way to install a 4-way trailer connector on your vehicle using this wiring harness. The T-connectors right here will plug directly into existing wiring so there's no cutting, splicing or tapping into the lines required.
The converter that they use is made using a surface mount technology to ensure superior performance. This harness will provide a 4-way flat trailer connector at the back of your vehicle. This will power your trailer's signal lights. This 4-way is compatible with 5-pole, 6-pole and 7-pole adapters that we do sell separately. This does connect quickly and easily. There's no cutting or splicing the wires.
Basically you'll locate the connection points at the rear of the truck, plug in these T-connectors and you'll be ready to go after you ground the white wire. This does include the taillight converter right here. This converter will ensure that your vehicle's wiring will match that of your trailer's. This converter is constructed using surface mount technology which has consistent, reliable performance. This will maximize your trailer light yield in the intensity while producing minimal heat. This does ensure superior operation in rough road conditions. Now all the parts shown here are included.
It comes with a nice set of colored, detailed instructions so you can see where it shows you where to install the harness. It comes with a piece of double-sided tape that is used to attach the converter to your vehicle. It comes with a grounding screw to get a good clean ground of the ground wire. It comes with some zip ties to help secure any loose wires and it comes with the dust cap for the 4-way connector. Basically what you can do is just pop this on and when you're not using it, when it's not connector to a trailer, you can just pop the dust cap right over to protect it. Then when you're going to hook up the trailer, you just plug it right in and you're ready to go. Now a few specs on this harness: The maximum amperage that it'll take for the stop and turn lights is 3 amps per circuit, for the taillights is 5 amps per circuit. Basically the way you'll go to install this is these T-connectors.
These will basically attach to the back of your taillights on your vehicle. What you'll do is the side right here that has the yellow in it, that's for the driver's side. You'll go to the back of the taillight, pop out the connection of the wiring harness to the taillight and just hook this T-connector right in. Then what you'll do is go to the passenger side. As you can see, it has a longer amount of wire so the green wire signifies that it's the passenger side. You'll just go all the way across to the passenger side. Do the same. Disconnect the back of the taillight, plug it right into here. Then you'll still have the white wire to attach and what you'll do is, it has the eyelet on it. Just connect this to a good clean ground using an existing screw or the included grounding screw that they include. With that all connected, you'll be ready to go. You can see your 4-way has a length of wire that you can just extend out so it'll hang out of the back of the vehicle. If you're not using it, just coil it up and store it in the back of the vehicle. That should do it for the review on part number C55513, the Curt T-connector Vehicle Wiring Harness with the 4-Pole Flat Trailer Connector. .
Average Customer Rating: 4.8 out of 5 stars (75 Customer Reviews)Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required. Converter is made using SMT to ensure superior performance.

Product shipped quickly for me. I spent 4 hours putting the wiring harness on my Toyota T100 because I installed the wiring in 1/2 wiring loom not provided, taped the loom in various places, and wire tied the loom up for a professional type job and so the wires would not be cut or rubbing on the frame. The instructions tell you that you must install the converter in the tail light compartment and then the grounding wire is not long enough to reach outside the compartment to attach to the frame or cross member. I got this all taken care of only to find out that my tail and brake lights worked properly but the left and right turn signal on the trailer would not function correctly unless you unplugged the flat four connector each time so the converter could reset. They were great about listening to my problem, even on Sunday, and are sending me a new wiring harness to replace the malfunctioning one I received but are not compensating me for any of my time or the tape and wire loom used. I have not received the new harness yet but will let you know what I think of the new harness after I get it installed for the second time. 219713

Haven't installed it yet, but arrived sooner than anticipated. Anticipate no problems as another reviewer installed the wiring on an identical T-100 pickup, and had nothing but positive comments about the installation and operation. 112637

Excellent product. I installed trailer hitch and trailer wiring harness by myself 2.25 hours. Etrailer 1st class. Fast shipping. No complaints at all. . 123562

This harness was a snap to install on my 2014 Toyota Tacoma. Instructions and video were dead on. You will be pleased if you purchase this product. Everything went seamless from order to delivery. 145601

So far everything seems ok. Took longer than I expected but we did a good job. 131214

The hitch receiver fit perfectly. It took a little over an hour to install with the aid of a small air wrench. The wiring took about the same and the instructions that came with it were quite helpful especially when removing the taillights on my Tacoma. Only issue I could see was the length of the Curt wiring harness. A slightly longer wire to run to the passenger side tailight would have made it easier to run along the Tacoma's existing wiring. Kudos to e-trailer.com for speed of order shipping. I ordered it on a Thursday and it arrived in Southeast Alaska on Monday morning. 186367

Bought hitch and wiring harness both from etrailer. Delivery was fast and Insolation of hitch and ele. wiring harness was simple and quick thanks to online videos . I like there service so much I ordered a set of tires for my trailer from them yesterday. I'm tellen ya, Its hard to find a company whom I will brag on, but I will be referring all my friends and family to this site for there automotive needs. This is my "go to" site for my needs from now on. No more high priced local stores here. Thanks guys, Great job. 182107
I purchased the Curt T-Connector wiring harness along with the Curt Trailer Hitch receiver for my 2010 Toyota Tacoma. Both came with complete installation instructions and illustrations. They were easy to follow and install. Installation time for both was about 2.5 hours, but I am 72 years old and don't move too fast anymore. The only help I needed was to lift the hitch to the frame and install the bolts to hold it up. Everything was of very good quality and I am completely satisfied. 170534

I just finished installing your wiring harness on my 2014 Tacoma. I had a question about removing my tail light so I called your 1-800 number. Within about 3 minutes my questions were answered. I love the idea that it just plugged in - no cutting or splicing! I have nothing to plug into it yet, but the tail lights work just fine, so I'm assuming a trailer's lights will work, too. It was a simple job which only took awhile because I wanted to wrap , tuck and tie everything up securely. 158272

Installed the etrailer hitch and wiring kit on my 2006 toyota tacoma last week. I could not be happier with the products. very good instructions and videos to help with install. I got a good tip on one video were the installer used tie down belts around tailgate so your bumper does not have to lifted off. I did it that way and worked great no lifting the heavy bumper done it all by myself. Great company! Plan on getting one for my wife's Honda CRV in the future. 184281

Easy to follow instructions, EXCEPT they would be better if they were in bigger print for those of us who have to strain to read them in their present size. It took me about 45 minutes to make the installation. I am currently under treatment for back problems, but was still able to crawl under to zip-tie the excessive wiring length. I will enlist a friend to attach the white grounding wire, but have all vehicle lighting working in its absence. 85510

Awesome product high quality cinch to install the irony was the part I replaced that failed was installed with the black switching box exposed to the elements. Henceforth the premature failure perhaps! At first couldn't figure out why I had to remove lens assy. but makes good sense to keep that part high & dry. P.S. Toyota has discontinued their part # for that harness! Got lucky when I found you. Keep up the good work. Thanks a bunch 201642
by: Etienne Dezentje04/13/2015
I just installed the Curt Class 3 hitch , the job went smoothly once my neighbor came over to remove the bumper. He ended up finishing the installation by himself. That's not like me to let someone work on my stuff , but he was having so much fun. The hitch looks and works great , the wire harness was a piece of cake. I used to wire vehicles for U-Haul back in the 70's when no wire harnesses were available. Great produce , thumbs up. 184880
by: Frank trucks in for service right now but I ll try07/31/2015
Great product very easy to follow instructions. I did go ahead and buy a bracket for the plug that attaches to a hitch. I'm sure I could have bought the bracket from you but didn't think about it until it was too late. Definitely will be buying more products from you as I'm doing my own tow package. Trucks in for service right now but I'll try to take pictures when I get it back. 215709

Product does exactly what is requires to operate lights on my 5x8 trailer. Brake lights, left / right turn, brake + turn, emergency flashers and side running lights all work perfectly. The etrailer agent lexis actually help me locate this package instead of a different package that was more expensive and not what I needed. Everything worked out perfect! 212115
by: N. Hartl07/01/2015
Everything fit perfectly. I would like to recommend adding one item to make the kit even better. Like most automotive wiring, it is contained in the black plastic split corrugated tubing. Adding a piece long enough to run from the left tail light to the right tail light and for a break out for the trailer connection would make the kit complete. 208593

As always etrailer provides great products with excellent product knowledge and support. I have ordered several products from etrailer with incredibly fast shipping which in my opinion combined with there product knowledge makes them a better option than any local supplier.Everything plugged into my existing wiring harness and worked great. 173426
Shipped out and arrived at my house within 5 days of ordering. The free shipping was nice. Install was easy and fast (would have been faster with an impact wrench) videos were very helpful. It looks great on my 2011 tacoma. Haven't had a chance to tow with it yet but im sure I will like the way it performs as well. 138728

Don't pay anybody to this for you, it is so easy to install, I was going to have a shop install one me and then my buddy told me about etrailer.com so I took a chance and ordered one. I am glad I did. I had it install in 30 minutes or less. Hook up my trailer and all lights worked fine. Worth every dime. 198576
Product worked great easy to install in about 45 mins with directions. Comes with all hardware and zip ties, double sided tape, and screw for the ground wire. Only thing I didn't like was the wires were a little too long so I had to take the slack out with zip ties but better to have more than less. 191020

My local dealers wanted hundreds of dollars to install the trailer wiring for my 2014 Tacoma. Instead I purchased the wiring harness from etrailer.com and saved a lot of cash. The instructions were easy to follow and installation was done quickly by me. End result: all lights worked perfectly! 185497
I've placed two orders with etrailer now have had excellent service. My orders have been shipped and arrive quickly. The products have been as advertised. The receiver hitch was an easy installation. I've been very happy with etrailer and would definitely recommend them. 193865
by: Lance M10/03/2013
Had everything I needed and very easy to install the bonus thing with this item was the circuit short protection for the module and vehicle it is installed on. This will save on fuses. How it works it will keep shutting down until you get the short fixed on the trailer. 102483
Kit came very quickly and was super easy to install. It took longer to ziptie i to the frame of my truck. The kit works perfectly and I had no issues putting it in since it was plug and play. Very happy with the wiring kit and the excellent service from etrailer.com! 78410
by: Ken N.08/19/2015
The product arrived when scheduled with all required parts in the box. Instructions were clear and easy to follow for both the trailer hitch and the T-Connector Wiring Harness. Installation of the wiring harness took approximately 15 minutes with no problems. 220321
by: Brent G.01/25/2014
With the exception of having to use a crowbar to spread the brackets far enough to mount to the frame rails, installation went as anticipated. Kudos to Ron C. for his tip on supporting the bumper to the tailgate while installing, much easier. 114745
by: Tom M.03/23/2015
Curt hitch did not fit the 2012 Toyota Tacoma. The distance between the vertical plates on the hitch is 37 1/16 inches. The frame rails on the truck have an O.D. of 37 7/16 inches. So the hitch is 3/8 inch too narrow and wont fit. 180260

I am not a "hoods up" backyard mechanic type guy. Therefore I was a little hesitant to try this product. However, it was so easy and the online video so explanatory I did it in 45 minutes or so. I am extremely pleased!!! A+++++ 113971
Haven't installed yet, last one worked fine for a year but got wet, damaging the circuitry. New England winters are hard on vehicles. Will try sealing the seams on this controller with Quad Clear and see how it works out. 167999

This wiring harness was a very easy install. Kit is professionally made just like it was part of my 2014 Tacoma. Plenty of wire length, connectors snap in perfectly. No way could a novice mess this up, it's idiot proof. 122258
Great product. This harness was insanely easy to install and came with everything it needed, zip ties and two sided tape included. If you have A 10mm wrench you can be tow ready in literally 5-10 minutes. 187948

My wife and installed the wiring harness and hitch on my 2010 Tacoma without issue. We are not mechanically inclined, but a combination of videos and the manual made the job easy. 146287
No cutting at all, and everything ziptied into place. Cathy at eTrailer also did a great job. 55 bucks to avoid lots of wiring or sucky Scotchloks is money well-spent. 167199
Wiring harness was very easy to install, took all of 5 minutes. If I need to order more or if other people need a wiring harness I will refer them to this product! 168194
